Doing some research, I happened on to Prison Talk, a site loaded with information for people like me. It includes a forum where you can find support, ideas, information, and some people with truly big hearts. The "Loving a Sex Offender" forum is especially useful.
You will need to register in order to see the LASO forum but it will be worth it. I promise.
The forum is enormous and I haven't quite figured out how to navigate easily...but I'll get there.
